大連膠管在使用前，必須先把膠管內壁(bi)滑石粉吹除(chu)干凈，防止(zhi)焊割(ge)炬(ju)的(de)(de)通道(dao)被(bei)堵塞。在使(shi)用(yong)(yong)中應避免受外(wai)界擠壓和機(ji)械損傷，也(ye)不得與上述影響膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)質量(liang)的(de)(de)物質接觸，不得將管(guan)(guan)(guan)身(shen)折疊。煤(mei)炭(tan)工(gong)業(ye)用(yong)(yong)油(you)管(guan)(guan)(guan)主(zhu)要(yao)(yao)有(you)(you)液(ye)壓支架膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)管(guan)(guan)(guan)。近年來，有(you)(you)些煤(mei)礦液(ye)壓支架的(de)(de)壓力要(yao)(yao)求已(yi)經提高，一部(bu)分鋼絲編(bian)織膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)不能滿足其性能要(yao)(yao)求，要(yao)(yao)求改用(yong)(yong)鋼絲纏(chan)(chan)繞(rao)油(you)管(guan)(guan)(guan)。此(ci)外(wai)，為(wei)防止(zhi)煤(mei)礦井(jing)下采煤(mei)過(guo)程中煤(mei)塵(chen)污染和提高生產安全(quan)性，增加了(le)煤(mei)礦用(yong)(yong)油(you)管(guan)(guan)(guan)的(de)(de)品種，如煤(mei)層探水封孔器(qi)伸縮油(you)管(guan)(guan)(guan)，用(yong)(yong)于(yu)煤(mei)礦井(jing)下工(gong)作面綜采前對煤(mei)層進行注(zhu)(zhu)水、注(zhu)(zhu)漿(jiang)等作業(ye)。據報道(dao)，國內已(yi)有(you)(you)廠家生產，并經十(shi)幾(ji)家煤(mei)礦試(shi)用(yong)(yong)，可替代同類進口產品。膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)(jiao)帶的(de)(de)發展，膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)發展的(de)(de)重點是提升(sheng)汽車用(yong)(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)制造技術和產品性能，填補國內高檔(dang)汽車用(yong)(yong)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)(jiao)帶的(de)(de)空白。加快高壓鋼絲編(bian)織膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)膠(jiao)(jiao)(jiao)帶和纏(chan)(chan)繞(rao)膠(jiao)(jiao)(jiao)管(guan)(guan)(guan)的(de)(de)更新換代速度，提高脈沖(chong)壽命(ming)。
